Breaking SHA1-HMAC
#1
I am new to hashcat and trying to do a simple experiment.

I generated a hash using the following:

echo -n "abcd" | openssl dgst -sha1 -hmac 1234

It generated a hash:
8717c25d45b7c48e66d917255c6e5b9e15edc46c

I would like to use hashcat to break this. How will I do it?

I tried using the following and it gives me an error: line length exception

hashcat-cli64.bin -m150 -a3 hashfile outputfile

I have the above mentioned hash in the hashfile.

I also have a GPU but I am NOT running oclHashcat-plus.

I really appreciate any help.
